Comment

In the 1920-1940s, Shanghai banks - such as the Tokyo Koshinjo, Limited - were often requested to make investigation on Shanghai-based advertising agencies, in order to evaluate their solvability. These investigation offer a rich source to document the history of advertising agencies (date of founding, incorporation, status, founder and manager, autorized capital, clients, etc.).
